Karl Curio’s cry pierced the garden before his servants could fathom what had transpired. He was returning from an evening stroll alongside Joseph Johann Kirchner, the painter to whom he had granted shelter under his roof; mere moments earlier, the two men had been walking side by side. Curio staggered indoors with his face bathed in blood, crying out that his companion had struck him down. Kirchner was no longer upon the garden path. At his trial, the painter maintained that an unknown assailant had slipped between them; the jury, having weighed the testimonies of witnesses and physicians alike, gave no credence to his tale.
The proceedings opened before the Vienna Court of Assizes on 18 June 1888. Kirchner’s reputation had preceded his arrival in the dock: an artist of esteemed draughtsmanship, eccentric and at times singular, he had likewise endured years of instability and debt. Yet the court was summoned to judge a precise act committed in a garden in Döbling, not to pass sentence upon an entire life. It fell to the jury to decide whether the blows dealt to Curio constituted an attempt upon his life, whether Kirchner had delivered them, and whether his faculties had been sufficiently deranged to relieve him of penal responsibility.
Kirchner had embraced painting against the wishes of his father, who intended him for commerce. Having studied at the Academy of Fine Arts, he devoted himself to landscape painting and earned his bread by illustrating periodicals. In 1873, he wed the daughter of his landlords, to whom his hand had long been promised, and two children were born of the union. A few years later, he abandoned the conjugal hearth to dwell with Marianne Rössel, a widow encountered during an excursion, though he continued to provide for his wife and offspring. His earnings were at times substantial, yet the upkeep of two households, frequent changes of lodging, and commissions accepted only to be neglected eventually plunged him into debt.
In November 1886, he made the acquaintance of Karl Curio. The man of independent means soon offered him hospitality at his residence in the Hirschengasse, granting him two rooms in an outbuilding and a seat at his table. Kirchner accepted these generous terms while secretly entering into an intimate liaison with Klara, his host’s wife. Their clandestine meetings were kept in an apartment rented for that sole purpose. Marianne was privy to the affair, demanding only that Kirchner reserve two evenings each week for her company. Klara, for her part, remained financially dependent upon her husband; she received an allowance from her parents to defray household expenses, yet nothing proved that she would have enjoyed unconstrained disposal of Curio’s estate in the event of his death.
On Saturday, 14 January, the two companions prepared to attend a masked ball. Kirchner donned a fur cap and concealed his opera hat beneath his coat; Curio placed a hunting cap in his pocket and wore his opera hat. Together they descended into the garden. Between the trees, the path narrowed. Curio walked ahead. At that spot, by his own account, he was struck from behind by a blow that shattered the frame of his hat, followed by a second that laid open his temple; raising his arm, he warded off a third strike. He caught no glimpse of his assailant, but his suspicions fell instantly upon Kirchner, and he fled back toward the villa crying his name aloud.
Klara hastened to his aid with water, only to slip back down into the garden. Her conduct there became one of the most fiercely contested points of the trial. She subsequently maintained that she had merely called for the gardener and urged Kirchner to flee, whereas several domestic servants attributed words to her that seemed to lament that Curio had not been more grievously struck. She did not appear before the court. A medical certificate from Munich attested that she was suffering from severe nervous prostration. The tribunal accordingly read her prior depositions into the record, but she could not be cross-examined before the jury.
Curio’s wounds healed within a few days. The physician summoned during the night determined that Kirchner’s walking stick, loaded with a ball of lead, could have inflicted the injuries and might well have proved fatal had the blow fallen with greater force. The weapon had been recovered in the garden. Klara subsequently displayed it to the servants, asserting that it bore no trace of blood—proof, in her eyes, that her husband had not been struck with it. This detail failed to lay the question to rest: did the absence of blood suffice to exonerate Kirchner, or had the blows simply landed with less penetration than the prosecution maintained?
Apprehended two days after the assault, the painter declared that a third man had suddenly stepped between them, struck Curio, and fled into the darkness. He described a stranger of slighter build than himself, clad in a pointed cap. He insisted that terror had frozen his limbs, and that only later had he grasped that suspicion would inevitably light upon him. Yet he had penned several farewell letters, borrowed a revolver, harboured thoughts of self-destruction, and even contemplated slaying Marianne and their child before sleeping. In a missive addressed to Klara, while denying the attack, he alluded to those “schemes” which chance had brought to ruin. For the prosecution, these words, alongside the abandoned weapon and his flight, laid bare the design behind the violence; for the defence, they betrayed only the panic of a man who believed himself already condemned.
The question of pecuniary gain divided the parties with equal sharpness. The public prosecutor contended that Kirchner sought to do away with Curio so that Klara might command his resources and maintain her lover. The defence countered that this fortune was not Klara’s to bestow: she drew only an allowance, and nothing established that she could have obtained unfettered administration of her husband’s property. Kirchner admitted to having received from her one thousand marks and a savings book, but presented these sums as loans or mutual aid between lovers. He had also accepted a piece of jewellery to sell on the eve of the assault, fetching forty florins for it. Such facts might fuel suspicion, yet they could not of themselves establish the motive alleged by the State.
Before the court, Curio spoke with firmness regarding the blows, but with reserve concerning the identity of his assailant: he had not seen him. Servants recounted Klara’s utterances; Marianne Rössel described Kirchner’s bouts of jealousy and his strange absences, at times so pronounced that she had feared for his reason. Friends depicted him as generous, conscientious, and incapable of doing harm to any living creature. The medical witnesses were not in complete accord regarding his antecedents, yet the court’s appointed alienists concluded that he was not labouring under mental disease at the time of the deed. The defence challenged their competence and petitioned for a supplementary evaluation, which the bench denied.
The proceedings thus resolved into a clash between two divergent readings of a single man. The prosecutor discerned in the debts, the liaison, the familiarity with the walking stick, and the letters a premeditated design followed by clumsy prevarication. Dr Benedikt, for the defence, portrayed instead an act of unreasoned impulse, the conduct of an exhausted artist whose faculties had momentarily given way. He underscored that Curio had survived and that his wounds were of no grave peril. The jury returned three findings: unanimously, they pronounced Kirchner guilty of attempted murder and affirmed the legal circumstance of *Tücke*, or treacherous assault; by ten votes to two, they rejected the plea of mental disturbance.
Availing itself of its statutory power of mitigation, the court sentenced him to six years’ severe penal servitude. The prosecution had demanded ten to twenty years; the judgment cited his unblemished record and the eccentric temperament attested by the physicians as extenuating circumstances. His appeal was dismissed. Kirchner entered the penitentiary at Stein on the Danube, but survived there only a few months, breathing his last on 13 April 1889. Shortly thereafter, Klara Curio petitioned for permission to pray over his grave and to erect a headstone in his memory.
The judicial dossier leaves behind a disquieting scene: a weapon bearing no visible stain, a victim who could not identify his attacker, a wife who shrank from public cross-examination, and a verdict that severed guilt from madness with rigid clarity. Justice ruled upon the evidence laid before it; as for Kirchner’s true motives, they remain entangled within the competing versions of the prosecution, the accused, and their intimates. In a nocturnal garden, three blows were heard; before the jury, it was the weight of what could be proven that determined the penalty.
